Just for the record... The Windows 2008 R2 (and Windows 7) guests are all 64-bit, with 4G of RAM each.
I'm trying it using VirtIO for both Disk and Network, configured during Windows installation (the second Virtual CD Drive contains: http://alt.fedoraproject.org/pub/alt/virtio-win/latest/virtio- win-0.1-81.iso ) Even when IDLE, W2K8-R2 crashes and, for example, if you try to install it as a Secondary Active Directory of another Windows, then, it crashes more often... I'm using SPICE / QXL for guest video. Anyway, I tried it with almost all virtual hardware combinations, starting from VirtIO devices, to IDE and e1000, VGA and etc... Every time it crashes. Also, VirtIO for Network is very unstable, both Windows 7 and Windows 2008 crashes when using it with OpenvSwitch bridges, when using that "default NAT from libvirt", it works better, so, I'm using e1000 from now on. Disabling KSM make it far more stable but, as I said, VirtIO for Net is still unstable (it gives windows BSOD). If you guys want (Serge), I can give root access to 1 or 2 Dell R610 with Ubuntu 14.04 + Qemu 2.0, so, you guys will be able to catch this problem while it happens... Since this problem is hard to reproduce, I'm available to help debug this, just let me know. BTW, I'm planning to try it with new QEmu 2.1 ASAP and/or with new Linux 3.16, on different servers, to see which one becomes more stable... Honestly, I don't know where the problem is located, I mean, it this a Linux or QEmu BUG?!
